The Research On The Yellow River Delta Wetland Ecological Protection Under Blue Economic Strategy

In order to further promote efficient ecological economic development of the Yellow River Delta, and perfect the national coastal economic layout, our country approve "The national high efficient ecological economic zone development planning of the Yellow River Delta" in November of2009. In April2011, the State Council passed "The blue economic zone development planning of Shandong Peninsula", Yellow River Delta development was pointed out as an important growth pole, and these are all the golden opportunities of sustainable ecological economic development of the Yellow River Delta. This paper conducts the research on Yellow River Delta wetland ecological protection under this background.The scientific project put forward by this paper is due to the poor Yellow River Delta wetland degradation situation. After the ecological protection and restoration in recent years, repaired results were visible that ecological environment has been improved, but ecological deficit is still very large. Especially at the background of the blue yellow economic, we must realize the "new structure crisis" in present economic development is not the traditional industry imbalance. The real crisis is that the ecological environment resources will become the serious supply "bottleneck" which restricts the sustainable economic development. Therefore, on aspect of Yellow River Delta wetland protection, we need consider its coordinated development with economic development. Based on many years’analysis on repairing progress of the Yellow River Delta, this paper studies the influence of social and economic factors on the ecological footprint and ecological carrying by ecological footprint model, and puts forward the corresponding development strategy to provide scientific reference for sustainable development decision.The main research conclusion and result of this paper:1. Under the background of high efficient ecological economic development strategy and blue economic development strategy of Shandong Peninsula, the harmonious development between Yellow River Delta wetland economy and ecology is the necessary premise of its sustainable development. Based on this, this paper conducts research on various industries’strategic development and puts forwards the thinking to harmonious development of ecological environmental protection and various industries in the future.2. The research result of the service value of wetland ecological functions of Yellow River Delta shows that the proportions of social economic value (function of supply and culture service) and ecological environmental value (function of adjustment and support) are quite equal. So, in order to strike the balance on the wetland development and ecological protection, the pursuit to the direct value of material is not enough.3. According to the model of pressure-state-response, this paper sets Yellow River Delta wetland health evaluation index system, conducts research by using analytic hierarchy process (AHP). The normalized index sort results shows:In characterization of the pressure index, the impact of anthropogenic factors such as social economic development level, sewage treatment, human activity intensity, wetland natural disasters on the ecological environment of Yellow River Delta is bigger than others; In the characterization of state index, water quality, soil pollution and degradation rate index of wetland has higher weight; In response index, the proportion of policy enforcement and environmental protection in production investment is much higher, that is to say, in the process of ecological environment restoration and protection, we should increase the investment of environmental protection and the formulation and enforcement of laws and regulations.4. In the calculation and research on ecological footprint model in the Dongying, through the calculation and analysis of ecological footprint, ecological carrying, ecological deficit (surplus) from2005to2010, the paper draws the following conclusion:the ecological deficit and ecological pressure index reaches its peak from2005to2010, the ecological deficit and ecological pressure index increasing year by year indicates that the increasing ecological pressure has become the bottleneck of coordinated, sustainable economic development of Dongying. 5. The calculation of ten thousand yuan GDP ecological footprint, ecological pressure index and sustainable development index from2000to2010shows that the ten thousand yuan GDP ecological footprint since2005is on slightly declining trend. During this period, the resources usage efficiency increases a little, the degree of dependence to ecological resources has steadily down, but resources transformation efficiency in production activities should be further improved. The rise of economic system development index mainly comes from the improvement of the ecological footprint. The improvement of ecological economic system development capability is only achieved by improving the diversity of ecological footprint and increasing the diversification of land utilization types.6. In the analysis of ecological footprint model of social economic driving force, this paper selects nine factors, including GDP, population and so on, as explaining variables, and ecological footprint as explained variable to carry out principal component linear regression analysis. And finally this paper gets the multivariate linear regression model of the ecological footprint size and its socio-economic driving force factors in Dongying from2000to2010. The paper further illustrates that social and economic development has strong driving effect on the per capita ecological footprint growth, finally, puts forward relevant measures according to models.7. As to wetland legal system construction, through various cases and practical survey, the paper conducts strong maneuverability research on introducing nongovernmental supervision mechanism, implementing "one area one law", solving the beaches ownership and promoting ecological legislation and so on.
